RAILROAD-Tl E.

SPECIFICATION forming part of Letters Patent No. 424,793, dated. April1, 1890.

Application filed December 26, 1889. Serial No. 334,972- (No model.)

To all whom it may concern;

Be it known that I, ABRAHAM KIMBER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Improvement in Railroad-Ties, of whichthe following is a specification.

My invention relates to an improvement in metallic railroad ties.

The object of myimprovement is to provide improved means for securingthe rails to the tie, all as hereinafter set forth.

The accompanying drawings illustrate my invention.

Figure 1 is a plan; Fig. 2, a longitudinal section, and Fig. 3 an endelevation.

A is a hollow iron beam open on the under side, and having at each endon the top surface gains 79, extending transversely across the tie andof suitable width and depth to receive the flanges of therails. Theouter edges 0 of gains 1) are undercut, so as to receive the outer edgeof the rail-flanges; but the inner edges are vertical.

For the purpose of strengthening the center of the tie between the railsand causing the weight of a train passing over the rails to operate toforce the ballast from the center toward the ends of the tie, and thuspack it most solidly immediately under the rails, I form a centralwedge-shaped transverse rib (I, having its point downward.

The rails are secured to the tie in the following manner: The uppersurface of the tie outside the rails is slotted, as at e, and isprovided on the under side on each side of the slot with an open bearingf.

Mounted in the slot 6 is a clamping-bar H, having on each side a pin 1',which rests in the bearing fl One end of the bar II projects over andfits upon the top of the outside flange of the rail J and against theweb of the rail, while on the opposite side of the pivot the barprojects over a wedge L, which lies on the top of the tie across theslot 6. Only one rail is shown; but the rails are secured to both endsof the tie in the same manner.

In operation the inner edge of the rail-flange is caught under theshoulder c. Clamp II is then put in position, as shown. Vedge L is thendriven under the outer end of the clamp, thus swinging the other enddownward and firmly clamping the rail to the tie.

I claim as my inventi0n- I11 a railroadtie, the combination of the rail,the tie having gain I), slot 6, and bearings f, formed in the sides ofsaid slot and open from beneath, clamping-har H, having pins 1', andwedge L, all arranged to 00-01)- erate as and for the purpose set forth.

ABRAHAM KIMBER.
